An unusual root resorption occurred after using hydroxyapatite particles for bone grafting in periodontal defects. This reaction, observed 9-10 months post-surgery, required restorative treatment.

Area of Science:

  • Periodontology
  • Biomaterials Science
  • Regenerative Dentistry

Background:

  • Vertical infrabony defects are common in periodontitis.
  • Hydroxyapatite particles are utilized as bone graft materials to treat periodontal defects.
  • Grafting procedures aim to regenerate lost bone and periodontal structures.

Observation:

  • A case report details an uncommon root resorption reaction following hydroxyapatite particle grafting.
  • Grafting was performed for infrabony defects on a maxillary canine and a mandibular molar.
  • Radiographic monitoring revealed root resorption 9-10 months after the grafting procedure.

Findings:

  • The observed root resorption is an unusual complication associated with hydroxyapatite bone grafts.
  • The lesions resulting from root resorption were successfully treated with glass-ionomer cement or resin composite.

  • Etiologic factors contributing to this specific type of root resorption are explored.
  • Implications:

    • This case highlights a potential, albeit rare, complication of hydroxyapatite grafting in periodontal regeneration.
    • Understanding the etiology of hydroxyapatite-associated root resorption is crucial for risk assessment and patient selection.
    • Further research may be needed to elucidate the mechanisms behind this reaction and refine grafting protocols.
